Sash-construction

ABSTRACT

A sash-construction having a notch against which a swing window or similar closing element, particularly a window swinging outwardly, is capable of being stopped, said window with its hinges is fixed to a separate narrow panel which is slidable in the plane of the normally closed sash and with the panel ends being guided with respect to the mutually parallel sash-sills. The ends of the narrow panel carrying the window hinges are in cooperative relation with a profile fillet applied to sills or posts. The slidable narrow panel carrying the window hinges is formed near its ends with a slipper or similar slide element, capable of slidably cooperating with the profile fillet present on the sill or post in question, while the edge of the panel carrying the window hinges abuts a case-shaped end of a profile fillet fixed to a sash-portion in which case a resilient elastic draught-strip is secured.

I N VEN TOR. JORDAAN KNAPP Adm/M06 1 026/7449 W AT TORNEYSSASH-CONSTRUCTION This invention relates to a sash-construction having anotch against which a swing window or similar closing element,particularly a window swinging outwardly, is capable of being stopped.

In practice, especially in high-rise construction, difficulties areexperienced when cleaning the windowpanes on the outside. When thedimensions of the window are not too great, one may manage with a handtool such as a cleaning gear held in a clamp which is fixed to a pole.This, however, is uneasy and certainly not undangerous. With somewhatgreater window dimensions it is not possible to clean the window on itsoutside from inside.

The invention has for its objective the provision of a sashconstructionof the type described above wherein the disadvantages picturedhereinabove are removed. According to the invention this is achieved inthat the window with its hinges is fixed to a separate narrow panel partwhich is slidable within the closed plane of the sash and with its endsguided with respect to the mutually sash-sills. The narrow panel isfurther preferably provided with one or more ventilation windows orgrids which are selectively openable.

The construction of the invention makes it possible to move the attachednarrow panel window in its opened position together with the part as aresult of which and through the related formed opening, the outsidesurface of the window becomes accessible and can be cleaned from insidethe buildmg.

The invention may be applied to a window as well as to a door, both ofwhich are rotatable on a horizontal shaft. In the latter case thewindow, in its center, is made to hingedly rest on brackets, whichlatter in turn are hingedly fixed to e.g. the sash-posts.

It is efficient when the ends of the panel carrying the window hingesare in cooperative sliding relation with a profile fillet as applied tothe sills when the sash and panel move horizontally, or as applied tothe posts of the sash when the sash and panel are mounted to movevertically.

For reducing friction, the slidable panel part carrying the windowhinges is formed near its ends with a slipper or similar slide element,capable of slidably cooperating with the profile fillet of the relatedsill or post part of the window. This mea sure ensures an easy slidingof the panel part carrying the hinges, thereby doing away with thenecessity of chiseling out special grooves.

For achieving an efficient sealing, the longitudinal edge of the panelcarrying the window hinges abuts a case-shaped end of a profile filletfixed to an adjacent edge of the related sashpart, in which case aresilient elastic draught-strip is secured.

The invention is explained below with reference to the drawing, inwhich:

FIG. 1 shows shows front elevational view of the sash-com struction ofthe invention with the window in its closed position.

FIG. 2 is a front view of the sash-construction of the invention withthe window opened and moved into a position in which it can be readilycleaned from inside and FIG. 3 enlarged, fragmentary crosssectional viewtaken substantially on the line IlI-IlI of FIG. 2.

FIG. 4 a similar cross-sectional view taken on the line IV-IV of FIG. 2.

The sash, which has opposite top side, bottom side, and lateral sideportions, and may consist of wood is represented by 1, while the window2 is provided with a window pane 3. The window 2 is swingingly mountedin the sash by means of suitable hinges 4 and is designed preferably tobe swung outwards. According to the invention the hinges 4 are fixed ina narrow panel or part 5 which is disposed slideably in a crossdirection, i.e. within the closed plane of the window and is guidedtherein on the upper sill 6 and the lower sill 7. Panes 8, 9, 10 or 11can be arranged in the part 5, or ventilation grates or the like which,if desired, may be of the type admitting of being selectively closed oropened.

By moving the panel 5 as shown in FIG. 2 when the window is opened, asecond opening 12 is provided enabling the window 2 to be cleaned in itsopened position from inside.

A normal dog-lock is represented by 13 in FIG. 2 with the aid of whichthe window 2 can be locked in its closed position.

The sash-sills 6 and 7 are formed with a suitable profile fillet ortrack 14 as represented in section in FIGS. 3 and 4.

A glider or glide shoe 15 secured to the panel 5 by means of a T-profilebracket 16, as with the aid of screws, is complementally formed with atrack or guideway to be in cooperative sliding relation with saidprofile fillet 14. The glider l5 may be made from synthetic materialwhereas for the track or profile fillet 14 and/or the T-profile 16,respectively, preferably a noncorrosive material, such as aluminum ischosen.

On its outer face side of abutment with the window 2, the profile fillet14 is formed with a grooved case 17 in which the thickened portion of adraughtproof means 18 in the shape of a resilient weather strip issecured. Furthermore the case 17 forms the stop for the window 2 in itsclosed position.

The lower sill 7 is also provided preferably with a similar profilefillet 14 which cooperates with a like glider 15 which is secured to thepart 5 in the way described hereinbefore. Said profile fillet 14, asshown in FIG. 4, has also as its object to guide the spanner or thecasing 19 ofa window adjusting rod.

As shown in FIG. 1, in the closed position of the window 2, part 5 abutsthe turned-off resilient strip 20 embedded in a profile fillet in aknown manner. Thus an efficient draught exclusion is provided betweenthe panel 5 when it abuts the sashpost 21.

It should be observed that the details as shown in FIG. 3 have beenomitted from FIG. 4 because the view is taken on line lV-lV at a pointbeyond the lower glider, wherein the profile fillet is in cooperativerelation with a like glider which is fixed to the slidable window panelpart 5.

Though drawn and described with reference to a window, door or similarclosing element which is rotatable on a vertical hinge-shaft, theinvention may equally be applied, as already observed before, to anyelement capable of swinging around a horizontal hinge-shaft. The panelpart comprising the hingeshaft thusly is slidable in a vertical sense ismounted then for cooperation and slidable movement within and betweenthe opposed upright sash-posts. Then the closing element rests in itscenter hingedly on brackets which in turn are hingedly fixed to saidupright sash-posts 21.

It is apparent from the foregoing that a novelly improved frame and sashconstruction has been evolved which achieves the objectives andadvantages set forth throughout the specifi cation.
